My 01 Commander 21' Jet had 2 bolt on skags/fins that were thru bolted to the bottom of the hull, one on each side of the pump inlet area.  I let someone use my boat and it drifted up on a rock bar while they were on a float, so they broke off.  I've contacted Commander and they do not have a pair or know where to get them any longer.  Anyone have a pair they'd sell?  The picture shows what I have left of the ones that were on my boat(I jet ski'd to the rock bar and picked up my broken pieces  )

Already picked up a new rudder from Place Diverter.

They are on either/both side of the intake of the jet.  See pics attached...hard to get good pics underneath.  First pic from the front of the boat, second pic from the back of the boat.
